Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… … Wikipedia
Frequency modulation synthesis — In audio and music frequency modulation synthesis (or FM synthesis) is a form of audio synthesis where the timbre of a simple waveform is changed by frequency modulating it with a modulating frequency that is also in the audio range, resulting in … Wikipedia

Phase modulation — (PM) is a form of modulation that represents information as variations in the instantaneous phase of a carrier wave.Unlike its more popular counterpart, frequency modulation (FM), PM is not very widely used. This is because it tends to require… … Wikipedia
Phase distortion synthesis — is a synthesis method introduced in 1984 by Casio in its CZ range of synths, and similar to Frequency modulation synthesis in the sense that they are both built on phase modulation. Basically a sine wave is played, but by modifying the phase… … Wikipedia
